The Car Pool tube expands outwards and will remain in any position that you bend it. The head, or end of the tube, has a watertight seal that'll fit into most water bottles. Unscrew the top, and you're free to let loose.

The portable toilet is currently on Kickstarter, but you can get one by pledging as low as $19. Shipments are estimated to go out in March 2018. The Car Pool has already surpassed its goal of $5,000, so we expect you'll be seeing a lot of these in the next year.
